Goodyear Belts & Hoses 21022 Timing Belt Tensioner Hydraulic Assembly

The Goodyear Belts & Hoses 21022 Timing Belt Tensioner is a hydraulic tensioner assembly (also called an engine timing belt tensioner) for replacing a worn or leaking tensioner in an engine's timing system.

Key Features:

• Hydraulic assembly design that keeps the timing belt under proper tension
• Helps prevent belt slack and keeps the belt from skipping teeth on the pulleys
• Helps keep the crankshaft and camshaft(s) in sync so the valves open and close on time
• Replacement part from Goodyear Belts & Hoses, MPN 21022

Proper tension is critical to timing belt life and engine performance. A worn tensioner can lead to belt failure and serious engine damage. Check the tensioner whenever you replace the timing belt, and follow the engine manufacturer's recommended service intervals.
